Your not in any position to judge the standard - as you have nothing to compare it too. Ask around in your home country about the reputation and read PPrune and you'll then have something to compare it to - the general comments are not positive - think about this why do the majority of their students not return for the CPL - other than not being approved?
For conversion, some people who came for JAA and only got FAA, are going to Naples who apparently are doing the conversion after resitting all written exams, doing a few hours, and a skill test. I do not know the exact ins and outs of this though. Apparently the cost is somewhere between 1-2kUSD. I decided to "downgrade" to FAA, I decided that is the option that gives me the least stress about things.
Here in lies the next problem - did Naples get the written authority from the UK CAA under Article 8 of part FCL?
You can't just walk into a school and do a conversion anymore you must have written permission from a national aviation authority. Without this your training is worthless.
They may have just jumped from one school which is suspended - to one which is not equipped and upto date on the EASA regulations to provide the type of training required and then get their licence application rejected at a later date.
They should have learnt their lesson and had some personal responsibility but I'm prepared to bet otherwise....I'm prepared to bet they'll be able to add a second school to the list of those that took their money for providing a service they can't legally provide.
